Filed July 17,1961, Ser. No. 124,526 1 Claim. (CI. 20-48) This invention relates towindows and more particularly to a sash type window.

It is an object of the present invention to provide a sash type Windowhaving individual panes movable into the interior of the room forcleaning and maintenance purposes.

A further object of the present invention is to provide a sash typewindow of the type described which is extremely simple to install instandard frames, and which can be readily serviced whenever requiredwithout requiring access to the exterior of the building.

All of the foregoing and still further'objects and advan tages of thisinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawing,wherein:

FIGURE 1 is a perspective view of a window assembly made in accordancewith the present invention;

FIGURE 2 is an enlarged exploded fragmentary perspective view of certainoperating parts of the present invention; and

FIGURE 3 is an enlarged fragmentary cross sectional view taken alongline 33 of FIGURE 1.

Referring now to the drawing, a window assembly made in accordance withthe present invention is shown to include a window frame 11 havingguideways slidably receiving a pair of window sashes 12 forreciprocating longitudinal movement.

Each sash 12 is provided with a frame 14 hingedly mounted within anopening 15 thereof upon a hinge assembly 16 for selective movementbetween a normally coplanar position with the sash and an angularlyrelated position therewith for cleaning both sides of the window pane 18carried thereby from within the interior of the building.

Each frame 14 is provided with a hinge pin 20 which is normally receivedwithin vertically spaced apart recesses in one side of the sash 12, andwhich pin 20 may be removed in response to adjustment of a lock screw 22threadedly mounted within a fitting 24 secured to the bottom of eachsash 12. Thus, whenever it is desired to remove the entire frame 14, itis only necessary to thread the screw 22, thus raising the pin 20outwardly through the opening 26 in the top of the sash, thus making itpossible to withdraw such pin 20 and to remove the frame 14 from thesash.

Each frame 14 is also provided with a latch mechanism 28 for securingthe frame in the normally secured position within the sash.

While this invention has been described with particular reference to theconstruction shown in the drawing, it is to be understood that such isnot to be construed as imparting limitations upon the invention, whichis best defined by the claim appended hereto.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

A window assembly comprising, in combination, a frame having a pair ofvertically disposed guideways in each side thereof, a pair ofrectangular sashes each slidable in one of the guideways, and eachdefining an opening to be closed by a glass pane and a recess in oneface thereof encircling the opening, each sash being larger than onehalf of the frame to provide overlying ends when the sashes are movedaway from each other to fully close such frame, a pair of glass panes, apair of panel frames each encircling one of the glass panels andsupported in one of the recesses, one side of each panel frame forming ahinge, with the adjacent side of the sash supporting such panel frame,latch means releasably connecting the side of each panel opposite thehinge to the adjacent sash side, a pin vertically disposed through eachhinge, a fitting disposed in the bottom of each sash and having anopening aligned with the hinge pin thereof, and a pair of members eachthreaded into the opening of one of the fittings to retain the alignedpin in place.
